2 Claims. (Cl. 284-49) This invention relates to dispensers and, moreparticularly, to an improved dispenser for use in conjunction with beerbarrels and other liquid containers.

One object of the invention is to provide a dispenser which may bequickly attached to a beer barrel or the like and which will, whenattached, insure ready insertion of a draft pipe in the barrel forpermitting drawing of the contents thereof and without interfering lwithsupply pipes or the like.

Another object of the invention is to provide a dispenser which may bereadily attached to beer or other fluid containing barrels Without theneed of Wrenches or other tools, the use of which would interfere withthe tapping of the barrel.

A further objectof the invention is rto provide a dispenser employing aone piece body having a valve therein which will be operative forsealing the barrel or keg upon withdrawal of the draft tube without lossof pressure from the keg .or

barrel.

Another object of the invention is to .provide a dispenser having a onepiece body which forms a housing for `both the sealing valve and the gasinlet valve employed.

A further object of the invention is to provide a device of thischaracter employing an improved automatic inlet valve for gas orotherfluid under pressure. v

A still further object of the invention is to provide a vdispenserlwherein the liuid pressure valve employed eliminates the need forclosing valves on the gas pressure line when the gas pressure isrelieved from the barrel.

And a still further object of the invention is to provide a dispenser ofthis character Which is simple in constructionand which will be highlyelicient in use.

Other objects of the invention, not specically mentioned hereinbefore,will become apparent during the course of the following description.

In the drawing forming apart of my application,

Figure 1 is a vertic-al sectional View showing my improved dispenseras'it would appear in operative position on a barrel or keg, with adraft tube in position extending therethrough and into the barrel.

Figure 5 is a detail sectional View, partly in elevation, of the gaspressure valve.

Referring ,now more particularly to the drawing, wherein like numeralsof reference designate like parts throughout the several views, thenumeral I indicates in general the lbody of my irnproved dispenser. Thebody is formed with an exteriorly threaded depending tubular shank 2 onwhich is screwed -a connecting sleeve 3, said connecting sleeve having abayonet connection 4 for engagement with a lmating bayonet connection 5on the `top wall `6 `of `a barrel or keg. Carried within the connectingsleeve 3 is a com- .pression ring 8, anddisposcd beneath thecompressionring is a packing ring 9. As best `seen in Figure l, when the device is.installed on a barrel, Vthe connecting sleeve is screwed down upon theshank a suicient distance past the end of said shank so that the matingbayonet elements 4 and 5 may be `properly engaged. The sleeve 3 is,however, moved such a distance that, when the connecting `sleeve isrotated to lock the bayonet connection, the compression ring 8 willcompress the sealing gasket or packing ring 9 and 4thus insure a -tightseal between the body I and the head 6 of the barrel or keg.

The body I is Aformed with an integral upwardly enlarged valve chamberI0, .said valve chamber having a iiange II at its upper rim and 'beingformed with an ,integral gas linlet pipe I2', said gas inlet pipe havingYan enlarged free end portion .defining a combined coupling and gaspressure valve element I3, said gas pressure valve construction to bedescribed in more detail hereinafter.

Normally closing the ktop of the valve chamber I0 is a cover I4, saidcover v,having a wall I5 ,and an integral gland I6. The `wall I5 is.secured to the `'lange II of the valve chamber rIIII by means of screwsIl, ,a suitable kgasket I8 being disposed between the wall I5 and theupper `surface ,of the rim II to prevent leakage. The Wall ,I5 isprovided with an axial opening ,I9 which cornmunicates betweentheinterior of' the gland ,I6 and Vthe interiorof the `,valve chamberIll, said opening `being in vertical alinement `with the ltubularshank`2, which shank .is .in communication with the interior ofthe valvechamber I0 .and the interior ofthe barrelor keg LI. 4Mounted within thegland I6 Aand extending about vthe opening .I v9 thereabove isa packingWasher 20. .As will beseen in Figure 1 ,'the .gland 'I6 is interiorlythreaded and receives thethreaded shank 2l of a sealing nut 22, the nuthaving a relatively large manually engageable portion 23. Attention isparticularly called to the fact that the lower edge of the opening I9defines a valve seat, which, for convenience, has been indicated at 24.

The wall I has mounted on its lower surface a yoke 25. The yoke 25hingedly mounts a valve member 2S, said valve member having an attachingshank 2'I, which extends between the arms of the yoke 25 and isswingingly connected therewith by means of a pin 23. The valve member 26includes a circular supporting face 23 on which is mounted a valveelement 30 which is formed of rubber, liber, or other suitable material.The valve element 3o is secured to the face 29 by a screw having a roundhead 3|, the purpose of which will be set forth presently. The valvemember 26 is normally urged toward the valve seat 24 by means of aspring 32 which has a bow 33 engageable with the rear of the supportingface 29 and free end portions which are engaged with the wall of thevalve chamber I9, the spring having central portions coiled about thepin 29, as shown at 34.

The construction of the gas or fluid pressure valve will now be setforth in more detail. The gas pressure valve includes the couplingelement I3 and a detachable valve element 35, said valve elementincluding an inlet nozzle 33 which is reduced and ribbed to receiveconveniently the end or" a rubber uid supply tube 3l.

The valve element 35 is formed with a recess 33 which communicates Withthe opening 39 of the nozzle 35. The element 35 is formed with anintegral cage 40 which is formed on the end face 4I of said element,said end face 4I being flat and carrying a gasket 42. As will be seen,the gasket 42 lies against the flat face 4I of the element 35 insurrounding relation to the cage 40. The cage 40 defines a valve chamber43 which communicates With the recess 33. rIhe cage 49, further, isformed with a threaded mouth 44 into which is screwed a guide sleeve 45,said guide sleeve having an inner rim defining a valve seat 46.

Mounted within the valve chamber 43 is a spring pressed valve 4l, which,as best seen in Figure 5, is normally engageable with the valve seat 46.The valve 41 is formed with an axially disposed stem 48 which extendsinto the recess 38 and provides a guide for one end of anexpansionspring 49, the other end of said spring being engageableagainst the inner wall of the recess, said spring urging the valve 4ltoward the valve seat 46.

The coupling I3 is interiorly threaded at its base., as shown at 59, andscrewed into the threaded base is a valve opening element 5I, said valveopening element having an actuating sleeve 52 and a nipple 53, saidnipple extending into the pipe I2 which, as best seen in Figure 1, isformed with a slightly enlarged bore 54. Carried on the nipple 53 withinthe Ybore 54 is a rubber check valve 55. As clearly seen in Figures 3and 4 of the drawing, the coupling I3 and the valve element 35 areformed withl mating bayonet elements 5S and 5'I, the elements 56 beingmounted on the inner rim of the coupling I3 and the elements 5'I beingmounted on the free end of the cage 4D. As will be seen, the elements 5lare formed With inclined Walls 58 which ride on the inner walls 0f theelements 56. It will also be noted that the elements 56 arediametrically disposedon the coupling I3 and the elements 51 arelikewise disposed on the valve element 35.

In order to permit easy manipulation of the valve element 35, I providea handle 59 which is formed integrally on said valve element.

The operation of my improved dispenser Will now be described. Aspreviously stated, my improved dispenser is attached to the wall 6 of abarrel by engagement of the mating bayonet elements 4 and 5, theconnecting sleeve 3 being screwed on the shank to such a position thatthe ring 8 will compress the sealing ring 9 when the bayonet elementsare turned home. The valve member 25a of the dispenser will, when thedispenser is in inoperative position, be in engagement with the valveseat 24 for sealing the keg or barrel and preventing escape of air orgas therefrom. In this connection, it is desired to state that the checkvalve 55 will also operate to prevent escape of gas from the dispenserand keg.

When it is desired to draw from the contents of the barrel, it is onlynecessary to insert a draft tube, shown at 69, through the sealing nut22 and the body I into the barrel. The draft tube when being moved tooperative position, will function to drive the bung in the bunghole 6Iinto the barrel. After the draft tube has been moved to the keg orbarrel the nut 22 is turned for engaging the sealing gasket 20 tightlyabout said draft tube for preventing leakage. It is desired particularlyto call attention to the fact that, as the draft tube moves downwardly,the end thereof engages the round head screw 3| of the valve member 25aand swings said valve member downwardly and laterally Within the chamberI9 to the position shown in Figure 1. The provision'of the round headscrew 3l prevents any damage to the valve element 33 by the end of thedraft tubewhen said valve is being unseated.

It is asumed for purposes of illustration that there is a sufficientamount of pressure within the barrel or keg to force the beer or otherliquid upwardly through the draft tube. If this condition prevails, thevalve element .will be out of engagement with the coupling I3. Asstated, the check Valve 55, together with the gaskets 9 and 2U, Willeffectively prevent escape of pressure from the barrel or keg. Let itnow be assumed that the pressure within the beg or barrel I is notsufficient to force the liquid through the draft tube. In order tosupply additional pressure, it is only necessary to attach the valveelement 35 to the coupling I3 This is done by manipulating the handle 5Sfor interengaging the bayonet connecting elements 56 and 5l. As thebayonet connecting elements are being turned home, the actuating 'sleeve52 will pass through the guide sleeve 45 and into engagement with thevalve 4l, thus unseating the valve and permitting flow of gas or otheriiuid from the tubeY 3,7, which is, of course, connected to asupply ofvfluid under pressure, through the bore 39, the recess 38the chamber 43,the element 5I and the check valve 55 into the pipe I2 and, thence, intothe cham*- ber I9 downwardly about the tube G0 into-'the barrel. When asufficient amount of gas under pressure has been placed in the barrel,it is only necessary to grasp thev handle 59 and partially rotate thevalve element 35 for permitting unlocking of the bayonet elements 56 and5l. Whenthis is done, the valve element 35 is removed from the, couplingI3, which acti-on will cause displacement of the actuating sleeve 52from the'guide sleeve 45A. The compression spring. `49'wi11 then urgethe valve 4l into engagement with thevalve seat 46 for stopping the 110Wof gas under pressure from the pipe 31.

During the operation of placing of gas under pressure in the barrel orbeg, the gasket 42 will effectively prevent escape of fluid from betweenthe coupling I3 and the valve element 35.

When it is desired to remove the tube 60, the nut 22 is loosened forloosening the packing 20. The tube is then withdrawn from the body. Asthe lower end of the pipe passes upwardly through the valve chamber I0,the valve member 25a will be urged by the springupwardly into engagementwith the valve seat 24. It is to be noted that the packing gasket 20 isdisposed above the valve seat so that said valve member will bepermitted to become fully seated before the lower end of the tube 69 hascleared the said gasket 20. It will thus be seen that there will be noloss of pressure incident to the removal of the draft tube from thedispenser.

Having thus described the invention, what is claimed as new is:
